; T0 cdl whom it may cancern:

Be it known that I, CHARLES VOLENTAR- SKY, e citizen of the Un1ted States, res1d1ng at.Cineinnati, in the county of Hamilton and State of Ohio, beve invented certain new and useful Improvements in AttlCh mente for Sole-Sewing Maehines, 0f Whieh the following is a specifieation.

My invention relates to an i1nprovement m a shoe sole sewmg mach1ne.

The object of the 1nvent1on 1s pnnmnly to provide un attachment far a sewing mai eh1ne, presentmg a eutter through the eye of the table operat1ng 111 advanee of the shoe.

needle, and also carrying e guide provding for a ready accese of the shank of the shoe to the table while the shoe is held in the verteal position necessary to secure a substantially vertieal, instead of the angularly inelined stiteh, Whieh results from the employment of this type of attachments beretofore in use.

f1111y set forth in the deseription of the neeompanying drawing, forming a part ai this specificati'on, in Whieh:

Figure 1 is a front elevation of the cmriage end its support, adapted to be appiied te e sole sewing machine currying the eutte1', guard and guide, likewise illustrating a portion of the sewing rnaehine table.- Fig.

2 is ELI1 end,elevation of the same. F ig. 3 is a seet1on on hne w, w, F1g. 1. Fig. 4 18 a detail top p]an view of guide, tube end guard, illustmting the position oeeupied by the cutter projecting into end through the eye of the table. Fig. 5 is a rear eevation of the emrier end portion of the guide.

In some style of shoes it is desirable te conceul or bury the stiteh securing the welt to the sole around the front portion of the This invention has to do with an attaehment for this work.

1 represents a support or braeket seeured te a sole sewmg mach1ne.

2 represents a carrier gibbed upon bracket 1, se as to slide thereon.

3 is a lever pivoted upon the sewing maehine -end eonneeted With the pin 1. of the earrier.

5 represents the sewing 1naehine table having the eye 6, through whieh the aw1 7 pnsses, the needle not being shown.

The carrier has an upwardly extended mm 8 upon which are seeured the guide 9 and the cutter 10.

11 is a spindle block having un orifiee in whieh the lower end of the eutter is adjustubly seeured by means of the screw 12.

13 represents pintle screws between Whieh the b1oek 11 is swiveled. By adjusting these pintles the point of the eutter can be longitudinally adjusted with referenee to the eye of the table without removing the cutter, and the eutter may be readily removed for grinding and the depth of the eut can readily be adjusted a1so.

The guide 9 is seeured to the arm 8 upon the other side from that upon which the cutter is attached. The guard is eurved forwardly end upwardly and has the foot 14 lying above and adjacent to the table. The concave portion of the guide 9 is beveled off et its front edge 20. Its curvature end rojecting in 1eur of the cutter afiord a "1'ee accese of the shoe shank to the table, allowing the shoe to be presented in substantially upright position thus insuring a vertically inserted stitch. The cutter is curved forwardly toward the table and inwnrdly toward the guurds for the smne purpose. Vhen the eurrier is thrown outward the pivotal mounting of the cutter relative to the stationary table withdraws the point of the cutter from the eye of the table, so that the shank can be stitehed without removing the attachments. Owing to the relative positions end eurvatures of the cutter and guard the shank of' the shoe can be presented to the table with the shoe upright, when the carrier is in forward position. If it were not for these features of construction the attaehment would have to be removed for stitching the shank, or else the shoe presented at such un angle thnt the resulting stitch Would be very angular.

15 is a braeket gibbed upon the earrier end secured thereto by screw 16, and currying a shield 17, preferably of flexible material, held by clamping plate 18. Ths shield at all times stands in front of the table and protects the 'shoe upper from the oil and WELX to which it would otherwise be exposed.

Guide 9 iS held on arm 8 by means of the screw 21, the head of Which is on the front of the arm, the inner end engaging nut 22 on the inSde of the arm, the nut being held by the pin 28 projeeted from guide 9. By this means the guide can be swung out of positon by loosening screw 21 from the front to give access to the sewing machine and it can be set in place end tightened from the front as the pin holds the nut stationary.

Having described -my invention, I claim 11. In un attachment for a sole sewng machine in combinaton with the table, a carrier, a; cutter and guide thereon curved inwardly end forwardly with reference to the table, and a shield adjustably secured to the carrier, substantally as described.

2. In un attachment of the class described, a carrier arm, a guide on the inside thereof, a, set screw having its head on the outside of the arm, a nut on the inside of the arni engaging the screw for securlng the guide to the arm, end a pin on the guide engaging the nut and holding it stationary, wherby ment to the carrier to the work support being curved in substantially parallel lines to eonform to the shape of a shoe upper in position on the machine, permitting a free presentation of the shoe, so that the needle wilIpass vertically through the Sole at the shank of the shoe.

In testimony whereof, I have hereunto set my hand.

CHARLES WOLENTARSKY.
